Mel B says Howard Stern, her fellow judge on "America's Got Talent," is kinder and sweeter than he comes across on television and his radio show.

"I did his radio show about 18 years ago and he was very feisty on the radio and as soon as the radio switched off, he was like a lovable teddy bear," Mel told Kit Hoover and guest co-host Michelle Beadle on Tuesday's Access Hollywood Live . "I don't think he wants anybody to know that, but yes, he is a softy pants!

"He does have an image where he can be a little bit feisty and that's what people expect and like, but he's actually a sweetheart," she added.
